I had the idea for this little scene before I did watch "Black Swan" - I

well, kind of tribute to Academy Award winner Natalie Portman ;)

Lovely. I especially like the worn marble floor, very natural.

As others have noted, fantastic.

There appears to be some light bloom at the bright highlights.  Was this
post-processed in, or an added (beneficial) effect from the focal blur?

There is one subtle touch you may look at adding (or maybe you have and I can't
notice..).  It appears as if the mirror is a mirrored surface, whereas mirrors
of this type are usually glass mirrors.  Mayber try adding a thin glass layer
between your mirroed surface and the swans, this can add two subtle effects
depending on the viewing angle: the reflection can get attenuated a bit and even
coloured slightly by the glass colour, and there will be a fainter, second
reflection on the glass surface.

in this case it just happened as a nice side effect from the focal blur, 
but in the past I did also use media containers for the whole scene (no 
need to mention that this sky-rockets the render time) and also simple 
post work by using filter functions of an image processing library I 
once did develop as my day-pay-job.

well, this is exactly what I did and it makes a huge difference compared 
to some simple reflective surface. It is a piece of glass (with fresnel 
reflection and all) and on its back side is a thin layer of silver.
You'll notice it if you look e.g. at the reflection of the upper wings 
of the black swan.

Thank you all for your kind word, much appreciated.

For some technical detail about the mirror see my response to Trevor and 
the only other technical aspect worth noting might be that there is in 
fact also the sunlight realistic reflected by the mirror and this did 
help in pronouncing the nice bright outlines for the back-lit swan figures.
A copy of the sun (with a slightly lower light intensity) was rotated 
below the horizon and projected_through the mirrors glass surface.

Cool, now that I have a closer look, I can see a slight double reflection.
Perhaps the scene contrast and perspective made it not so immediately obvious to
me at first look, maybe I should have looked harder...

Once again, very nice job though.

Me too!  First time around I didn't notice both the double reflection and the
extremely subtle and effective focal blur.  It just looked like an extremely
well shot photo.

Hey, Ive, could you elaborate on the table texture?  Any CSG or all meshes?

The marble texture is a proceduralized image map à la Tran/Piqueres. 
This pigment function is also used for the hight_field and also for 
creating a reflection map.
In general I do never use phong or specular highlights because a) this 
makes textures also work within radiosity-only (or MCPov) scenes and b) 
phong and specular looks always a bit like "old school CG fake" to me - 
mostly due the lack of fresnel falloff, I guess.

The mirror is CSG and is made (besides the mirror-glass) *completely* 
out of tori-segments. Swan figures and Trees are meshes. The Table is a 
height-field, the sky is a sphere the sun a disk and the world a plane.

Is the blurred reflected background due to
blurred reflection or due to focal blur?

the blurred tree reflection in the mirror surface is due focal blur and 
the reflection on the marble top is this + the "roughness" introduced by 
the high-resolution height_field used for it, err, I guess, as I have 
actually not really thought about it, it just did look right to me the 
way it happened ;)

ta da!  Completely accomplished artist, both in the stunning artwork and the
skillful craft behind it! You are another renaissance man!  :D

man, that's really awesome:  I expected the mirror would be a mesh too and
thought the background tree to be merely a background HDR image! O_o

I believe this deserves a HOF...

   Exactly the same feeling here... the revelation about the background 
left me really astonished. My brain automatically assumed such a perfect 
and beautiful lighting could only come from an HDR image.

   That was to be expected... sub-pixel detail can do wonders on that
regard if the focal blur has enough samples.

The chance to find a HDR-image with the desired sun altitude, a clear 
blue sky, some trees in the right position and a high enough resolution 
so the reflections are not already completely washed out seemed quite 
minimal to me.
On the other hand, it is all about high dynamic range and there is 
actually no need to use a ready-made image for this purpose, just 
appropriate values for 'emission' in the finish for the sky-sphere and 
the sun-disk.

...and I did forget to mention another simple trick. Within the image 
series for Vermeers atelier I did use his painting "View Of Delft" and 
did cut out the painted houses and added a transparency map for them 
within photoshop. These pictures of the houses are used as billboards in 
front of the 360° degree sky. The same method is used here but I did 
simply use a photo of a local park shot last summer and again did make 
the sky transparent.
This is useful for hiding any sharp transition from the ground-plane to 
the sky-sphere which might look distracting within reflections.

Alternatively, you may be able to stick on the edge of the disk and,

	Given the number of spaceships in the area, that would require a
once in a million chance ;) (of course, that is still better than in
the diskworld where the only “spaceship” was a diving bel

failure was the reason Rincewind was falling overboard in the first

	Although there is a disc-shaped world in Strata, it is not *the*
Discworld. Hence the distinction I made.
